OCO Order

An OCO (One-Cancels-the-Other) order is an order strategy consisting of two pending orders placed in opposite directions around the current market price, such that the execution of one automatically cancels the other.

How it works: A trader places a limit order and a stop order simultaneously—for example, a buy order on a breakout above resistance and a sell order on a breakdown below support. As soon as one is triggered, the platform immediately cancels the other.

Importance for traders:

• Allows trading on two potential scenarios without the need to constantly monitor the market.
• Reduces the risk of having two conflicting orders executed simultaneously.
• Useful during periods of anticipation ahead of major economic news or price range breakouts.

Common mistakes:

• Placing the two levels too close to the current price, causing one to execute prematurely without trend confirmation.
• Failing to follow up on the trade after execution to adjust stop-loss or take-profit levels.
• Relying entirely on the order without analyzing the broader market context.

An OCO order is often used by traders who anticipate a strong move without being able to pinpoint its exact direction in advance. Usage on the EVEST platform: The EVEST platform allows creating an OCO order by entering two linked pending orders in opposite directions. Once one executes, the other is automatically cancelled without manual intervention from the trader, saving the time required for real-time market monitoring.

When to use it: It is typically used when anticipating a price breakout in an undetermined direction, such as prior to major economic data releases that could move the price sharply either way, or when stepping away from the screen for an extended period while wishing to cover two potential scenarios.

Risks: During sharp and sudden volatility, both orders might briefly execute before one is cancelled due to minor technical latency. Additionally, misjudging the distance between the two orders can lead to an unwanted execution in an unintended direction.

Additional common mistakes: Some traders on EVEST place the two levels too close to the current price, triggering one due to ordinary market noise that does not reflect a genuine trend. Others neglect to attach an independent stop-loss to each leg of the order.

Connection to risk management: An OCO order helps predefine two clear risk management scenarios instead of making arbitrary decisions in the heat of the moment. It is recommended to adjust position size and stop-loss levels for each part of the order independently using EVEST tools, ensuring that potential losses remain within acceptable account limits.
